For what it’s worth, I’ve passed this comment onto the dev and they agree:

The airsonic one is quite slow. I had improved it over how slow it was originally… I should probably try examine it again and see if there’s any further ways to improve it

I can’t make any promises on their behalf (don’t hurt me, taiko), but the pace of this project has been incredibly fast for the past couple years and I wouldn’t be surprised to see some big improvements :)
